Made about £15 with dino sprint. It was never really about the money tbh, I just wanted people to enjoy something that I had created. It has 10,000+ downloads which im extremely happy with.

I'm in same ballpark, I have ads from which I made about $20 with 26k downloads (and 1.4k current installs), and I have in-game purchases from which I made 0. It seems some people really enjoy it, and give a good review, others post something like 'garbage' and give it a 1 star review https://play.google.com/store/apps/details?id=com.mildspring...
